| 摘 要： | 提出一种新的PCM（phase change memory，相变内存）和DRAM混合内存构架页面调度算法CLOCK-S。该算法根据一个内存页的读写属性以及相邻页的空间局部性，把该页调度到不同的存储器中，从而达到减少对PCM的写操作，延长其寿命的目的。该算法利用各个存储器的优点，避免其缺点。实验表明，相较于传统页面调度CLOCK算法，该算法可减少对PCM的写操作平均达10％。

| Abstract: | We propose a new page schedule algorithm for hybrid PCM and DRAM memory,called CLOCK-S.It schedules pages into different memories based on their access attributes and spatial locality of neighbor pages so as to reduce write count and in-crease endurance of PCM.This algorithm can make use of advantages of PCM and DRAM,while avoiding their defects.Our ex-periments show that CLOCK-S can reduce writes of PCM by 10%on average compared to the classic CLOCK algorithms. |
